Molecular cloning and Biochemical properties of GH-16 β-agarase from Gilvimarinus agarolyticus JEA5

Conference Dates

September 24-28, 2017


Agar is complex polysaccharide founds in the cell walls of some red algae and up to 70 % of the algal cell wall can be agar polymers. Agar was formed by a mixture of two polysaccharides named agarose and agaropectin.

Agarose can be hydrolyzed by α-agarase (E.C. and by β-agarase (E.C.; the former cleaves the α-1, 3 linkage of agarose to generate agaro-oligosaccharides, and the latter cleaves the β-1,4 linkage to generate neoagaro-oligosaccharides. Agarases have been isolated from many sources, including seawater, marine sediments, marine algae, marine mollusks, fresh water and soil. Recently, Givimarinus chinensis, G. polysacchalyticus, G. agarilyticus were identified and their agarolytic activity also reported. However, there are no report published that molecular and functional characterization of agarase from Givimarinus genus. In this study, we first report molecular characterization and biochemical properties of agarase from Gilvimarinus genus.
